At a glance, kendra believes that the function represented on the graph is linear.
how can kendra determine if the function is actually linear?
a. she can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
b. she can check to see if the sum of each y-value and x-value in every ordered pair is the same.
c. she can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
d. she can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

The resumâ´es of two male applicants for a college teaching position in chemistry are placed in the same file as the resumâ´es of two female applicants. two positions become available, and the first, at the rank of assistant professor, is filled by selecting one of the four applicants at random. the second position, at the rank of instructor, is then filled by selecting at random one of the remaining three applicants. using the notation m2f1, for example, to denote the simple event that the first position is filled by the second male applicant and the second position is then filled by the first female applicant, (a) list the elements of a sample space s; (b) list the elements of s corresponding to event a that the position of assistant professor is filled by a male applicant; (c) list the elements of s corresponding to event b that exactly one of the two positions is filled by a male applicant; (d) list the elements of s corresponding to event c that neither position is filled by a male applicant; (e) list the elements of s corresponding to the event a â© b; (f) list the elements of s corresponding to the event a âş c; (g) construct a venn diagram to illustrate the intersections and unions of the events a, b, and c.
